REFLECTOR FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 260,735, dated July 11,1882.

Application led May 31, 1882. (No model.)

.To all whom it may concern Beit known that I, HENRY F. BARTLETT, acitizen of the United States, residing at La Grange, in the county ofLewis and State of Missouri, have invented certain new and use` fulImprovements in Reflectors for Lamps; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure l of the drawings is a perspective View of my invention; Fig. 2,a sectional elevation; Figs. 3 and 4, detail views thereof, and Fig. 5 aperspective view in detail of the clamping device for securing thereflector tothe lamp.

The prsent invention has reference to certain new and usefulimprovementsin reiiectors for lamps; and the object thereof is to provide areflector simple in construction and capable of beingreadil y connectedto the ordinaryV handlamp, and removed at pleasure for cleaning or otherpurposes, or .when required to clean or till the lamp. These objects lattain by the construction substantially as shown in the drawings andhereinafter described and claimed.

In the accompanying drawings, Arepresents the reflector in the form of afrustum of a cone, covered at its back by a concavo-convex disk, a,provided with a suitable bail or handle, b, hinged, pivoted, orotherwise connected to said disk.

It' desired, in place of the reflector being in the form of a frustum ofa cone, as shown,with the disk connected to its back, it may run to apoint in the shape. of a cone, this change being made at pleasurewithout departing from the principle of my invention.

At the top ofthe reflector A is an opening, o, for the reception of theupper end ot' the lamp-chimney. This opening is preferably of the formshown in Fig. 3, and extends across the front edge of the reflector, sothat it can be removed horizontally without raising it up or beingcompelled -to first detach the chimney from the burner ofthe lamp.

VIhe reflector A, at its under side, has guideanges d, which tit overand upon a supporting-plate, B. This plate, at one end, has a clampingdevice for attaching it to the lamp, which consists of. a split springcollar, G, said collar passing around the collar of the lamp under theburner, and, if desired, the addition of a set-screw may be employed tomore firmly secure the collar in place around the collar of the lamp.

It lwill be seen that by the above construction, and forming thereflector with the opening extending across its front edge, therellector can bemoved Without handling and danger of breaking thechimney, the clamping device being left secured to the lamp.

The relector can be as readily and conveniently replaced, as it isdetached from the snpporting-plate B. The plate, being flat and ofconsiderable thickness and Width, forms a complete, strong, as Well assimple, support for the refiector.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

The reector' A, having at its top the open- I ingo, extending across itsfront edge, as shown, and provided at its bottom with guide-flanges d,yin combination with the hat supportingplate, B,having connected toit thesplit spring collar C, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my nameinv the presence of two witnesses.
